Kua tāruatia ki te papatopenga
\frac{8+3}{8}-\frac{3\times 4+1}{4}
Whakareatia te 1 ki te 8, ka 8.
\frac{11}{8}-\frac{3\times 4+1}{4}
Tāpirihia te 8 ki te 3, ka 11.
\frac{11}{8}-\frac{12+1}{4}
Whakareatia te 3 ki te 4, ka 12.
\frac{11}{8}-\frac{13}{4}
Tāpirihia te 12 ki te 1, ka 13.
\frac{11}{8}-\frac{26}{8}
Ko te maha noa iti rawa atu o 8 me 4 ko 8. Me tahuri \frac{11}{8} me \frac{13}{4} ki te hautau me te tautūnga 8.
\frac{11-26}{8}
Tā te mea he rite te tauraro o \frac{11}{8} me \frac{26}{8}, me tango rāua mā te tango i ō raua taurunga.
-\frac{15}{8}
Tangohia te 26 i te 11, ka -15.
